Pinch flats are a symptom, not a problem. Yea, the tire goes flat but if you have put the
proper amount of air in the tire to prevent the tire from bottoming out on the rim, pinch flats aren’t a problem. Tubeless users make the mistake of saying that they can’t experience pinch flat, which is true. But if you run too low a pressure, the tire can still bottom out on the rim and, instead of pinching the tube, the rim gets bent. Now you’ve traded a 25¢ problem for a $200 problem.
